Memory Subsystem Architecture
The memory subsystem architecture is dependent on the ProLiant Gen8 server platform.
For servers using the Intel® Xeon® E5-2600 family processor series:
16 DIMM slots: Four memory channels per installed processor with two DIMMs per channel for a total of eight (8) DIMMs or a
grand total of sixteen (16) DIMMs for the server. Up to 32GB capacity DIMMs are supported for 512GB of memory (16 DIMM slots
x 32GB per DIMM).
24 DIMM slots: Four memory channels per installed processor with three DIMMs per channel for a total of twelve (12) DIMMs or a
grand total of twenty-four (24) DIMMs for the server. Up to 32GB capacity DIMMs are supported for 768GB of memory (24 DIMM
slots x 32GB per DIMM).
For servers using the Intel® Xeon® E5-2400 family processor series:
12 DIMM slots: Three memory channels per installed processor with two DIMMs per channel for a total of six (6) DIMMs or a grand
total of twelve (12) DIMMs for the server. Up to 32GB capacity DIMMs are supported for 384GB of memory (12 DIMM slots x 32GB
per DIMM).
For servers using the AMD Opteron 6200 family processor series:
16 DIMM slots: Four memory channels per installed processor with two DIMMs per channel for a total of eight (8) DIMMs or a
grand total of sixteen (16) DIMMs for the server. Up to 32GB capacity DIMMs are supported for 512GB of memory (16 DIMM slots
x 32GB per DIMM).
24 DIMM slots: Four memory channels per installed processor with three DIMMs per channel for a total of twelve (12) DIMMs or a
grand total of twenty-four (24) DIMMs for the server. Up to 32GB capacity DIMMs are supported for 768GB of memory (24 DIMM
slots x 32GB per DIMM).

General Memory Population Rules and Guidelines:
Install DIMMs only if the corresponding processor is installed.
If only one processor is installed in a two processor system, only half of the DIMM slots are available.
To maximize performance, it is recommended to balance the total memory capacity between all installed processors and load
the channels similarly whenever possible.
When two processors are installed, balance the DIMMs across the two processors.
White DIMM slots denote the first slot to be populated in a channel.
Place the DIMMs with the highest number of ranks in the white slot when mixing DIMMs of different ranks on the same channel.
Do not mix UDIMMs, RDIMMs or LRDIMMs.
Quad rank RDIMMs are not supported in HP ProLiant Gen8 servers.
Quad rank LRDIMMs are capable of up to three DIMMs per channel.
RDIMMs operating at either 1.35V or 1.5V may be mixed in any order, but the system will power them at the higher voltage.
DIMMs of different speeds may be mixed in any order; the server will select a common optimal speed.
The maximum memory speed is a function of the memory type, memory configuration, and processor model.
The maximum memory capacity is a function of the memory type and number of installed processors.
To realize the performance memory capabilities listed in this document, HP SmartMemory is required.
